...者归纳三个必要条件如下:
(1)方法是虚的;
(2)有覆盖(override)产生;
(3)通过指针或引用调用相应的虚方法,而非通过对象调用;通过对象调用方法,无论方法是否是虚方法,均是静态联编行为。

What are file descriptors, explained in simple terms?
.... Some of the values of TYPEs are:
REG – Regular File
DIR – Directory
FIFO – First In First Out
But all file descriptors are
CHR – Character special file (or character device file)
Now, we can identify the File Descriptors for STDIN, STDOUT and STDERR easy with lsof -p PID, or we ca...
C++11 introduced a standardized memory model. What does it mean? And how is it going to affect C++ p
... performance and correctness of SC. For example, in certain architectures, FIFO write buffers are used by each core to hold the results of committed (retired) stores before writing the results to the caches. This optimization enhances performance but violates SC. The write buffer hides the latency o...

How to proceed with files that are sockets, pipes/FIFOs, block devices, char devices? Must hash them as well?

The main difference is fairness, in other words are requests handled FIFO or can there be barging? Method level synchronization ensures fair or FIFO allocation of the lock. Using
synchronized(foo) {
}
or
lock.acquire(); .....lock.release();
does not assure fairness.
